This invention relates to food choppers and more specifically to lthat typel of food chopper used for cutting food by hand.

One of the advantages of this type of food chopper is the large amount of cutting edge available, made possible by the arrangement of the knife edges. y

Another advantage resides in the arrange- Aient of parts, which provides easy access to all parts for cleaning. Vith this arrangement, the entire chopper may be disassembled by the removal of one clip and the parts taken out separately for polishing or cleaning or for sharpening the cutting edges. v

The particular advantage of this ,invention isv of manufacturing importance. The various parts are designed to be blanked out of suitable sheet metals. There is no soldering nor welding, and only two places of riveting are necessary in the entire construetion. This makes for eheapness of material and is most desirable from a viewpoint of economy in manufacturing, as it.con'iines the bulk of manufacturing costs to machinery operations, thereby eliminating ak big percentage of expensive hand labor.

The foregoing advantages together with all subsequent ones that may develop in the description, constitute my invention. which is more fully explained `by referring to the accompanying drawings, in which:

Figure 1 is a perspective view showing the device assembled, ready for cutting;

Figure 2 is a view of one of thetransverse cutting edges;

Figure 3 is a View of the othertransverse cutting edge; y

Figure 4 is a section on line 4-4 of Figure 2;

Figure 5 is a perspective view showing locking clip;

Figure 6 is a view showing the blank of the clip;

Figure 7 is a view the handle; and

FigureS is a view the circular cutting edge.

Referring to the drawings tailed description to Figure 1, in which the device is shown ready for operation, it is observed to comprise five parts. The upper portion, or handle, generally designated 1, the locking clip, generally designated 2, the circular eut'- ting edge, generally designated 3, a transshowing the blank of for a more deshowing the blank ofv thereof, and particularly n verse cutting edge generally designated 4, and a second transverse. cutting edge generally designated 5.

Taking the parts up in the above order, in Figure 7 a blank of part 1 as it is struck from suitable sheet metal isy shown. By eX- amining it, there is apparent a central strip from end to end. The two portion 7 running ends of portions 7 are provided with holes 8-9--10-11. Starting at the upper end, below the holes S and 9 there are provided wing like port-ions 12 and 13, adapted to be `bent bac r underneath on the dotted lines 14 and 15, thus forming the upright part of the handle designated by the numeral 16. The slots 17 are designed to relieve the bend and allow the corner to be formed. Circular portions 19 furnish they ears to lock and strengthen the corners and are best shown in Figure 1.

Continuing below the eared portion there are provided two wing portions 22 and 23, designed to be bent back underneath on the dotted lines 24 and 25. This provides the side of the handle as best shown in Figure 1. On each end of these wing portions there are provided ears 27 which are designed to be bent over the central portion 7 and strengthen the handle as shown in Figure 1. l

Following below this there is a repetition of slots 17 and wing portions 28 and29 are designed to be bent back underneath along the dotted lines 31 and 32. This .forms the other upright part of the handle designated in Figure 1 by the numeral 33. t the lower end of the wings 28 and a right angle bend downward is made in the central strip 7.' The elongated wings 34 are bent back on top, and form lugs 35, best shown in Figure 1.

It is to be understood that the right angle bend is put in only after all the forming of the strip has taken place. Below wings 33 and there are wings 36 and 37 which are formed to be bent back on top, on lines 38 and 39. This forms the cross'portion designated by numeral 40 in Figure 1. Holes 41 and 42y and cuts 43 and 44 are suitably located so that on bending they form cuts 45, Figure 1, and ears 46, Figure 1. Ears 47 and 48 are provided on the end ofthewings 36 and 37. These earsare bent to form lugs 50 in Figure 1. Slots 51 and 52 are provided with central portion 7 to take the undercut lugs 53 and 54 shown on the cuttingdolade generally designated 5. At the lower edge ol the wings 47 and 48 a right angle bend is made that brings the holes 10 and l1 into alignment with the holes 8 and 9, respectively. These are fastened together with rivets 55 and 56, shown in Figure l. The above struct-ure provides the handle.

The locking clip is blanked out of suitable spring metal, in the shape el a cross shown in Figure 6. The arm 5 is struck `up as at 6l, Figure 5, and forms a linger hold. The elongated wings 62 and 63 are shaped to `form spring clips 64; and 65, Figure 5. The body portion 66 is provided with a notch 67 in the end opposite the linger hold, which notch engages the notch 68 let into the back ot' lug on cutting edge generally designated 5. The above structure forms a spring clip that can be pressed into locking position as shown in Figure l, and can be lifted out of locking position by the tip of the linger. The spring clips 64 and 65 lit into the cuts provided on the handle.

The circular member generally designated 3 is blankcd out of suitable cut-ting material and furnished with a cutting edge 70 on one edge. rlhe other edge is provided with undercut lugs 71 and 72, the top part of which are crimped back on themselves on the lines 73 and 74. rlhese furnish two of the hook members that hold the handle to the cutting blades. rlhe other two hook members 75 and 7 6 are identical. in termation. Two other members 77 and 78 which are slotted as at 8l are provided to be bent over on the dotted line 7 9 and 80, and form holding lugs 82 and 8f3 into which is slipped the cutting blade generally designated ll. The blank is then bent into a circle and joined either by welding, soldering, crimpor riveting. ln this case rivet holes 90 are provided.

The transverse blade, generally designated d, is formed of suitable cutting metal, provided with a cutting edge 85 and a Slot 86.

The other cutting member, generally designated 5, is termed or' suitable material and provided with a cutting edge 87, and a slot 88, and aforo-mentioned lugs 53 and 54, said lugs 58 and 54.- are crimped over at the top as shown in Figure 4l.

rlhe live parts of the device are quickly assembled, by placing slot 86 et blade l into slot 88 of blade 5 and then by holding the blades at a right angle, the cutting edges are brought flush. The blades held at a right angle are then placed within the circular member 3, the tip oil? blade l litting into the slots 8l. The slots 5l and 52 in the handle are then slipped over the lugs 53 and 54. The lugs 35 are slipped under the hook 75, while the lugs slip under the hooks .7l and 72. The slots 5l and 52 aresuiliciently long to permit a longitudinal sliding of the handle inte a locking position, hereinbefore described, and the device is ready for chopping.

It is readily seen that a sturdy chopping mechanism is thus assembled in a simple, certain way.

The above constitutes a minute description ot my invention, which is susceptible to certain variations and modilications, without departing from the spirit of the specilication, drawings or appended claims.
